9 MAJOR POSITIONING CONTROL
[2] 4-axis linear interpolation control (INC linear 4)
Operation chart
In the incremental system 4-axis linear interpolation control, using an address
established by a machine OPR in the 4-axis coordinate plane, a linear interpolation
positioning is carried out from the current stop position (start point address) to a
position at the end of the movement amount set in the "
Da.6
Positioning
address/movement amount". The movement direction depends on the sign (+ or -)
of the movement amount.
Restrictions
An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning
operation.
•
If the movement amount of each axis exceeds "1073741824 (=2
30
)" when "0:
Composite speed" is set in "
Pr.20
Interpolation speed designation method"
... The "Outside linear movement amount range error (error code: 504)" occurs
at a positioning start.
(The maximum movement amount that can be set in "
Da.6
Positioning
address/movement amount" is "1073741824 (=2
30
)".)
